P31-NMR spectrum of the corrosion of schreibersite. An amount of 0.5 Fe3P powder was placed in 15 mL of water for 1 week under a 20% mixed CO2/CH4 and 80% N2 atmosphere. The water contained multiple phosphorus species, including reduced phosphorus species, such as hypophosphite (H2PO2) and phosphite (HPO32−).
